The Effect of Urban Air Pollution on Glazing Daylight Transmittance—a Model Study
This study investigated the change in glazing daylight transmittance due to the deposition of urban airborne pollutants using a seven-sided glazed building model in a large city centre. The model was constructed with four vertical surfaces, two surfaces inclined at approximately 45° and one horizontal surface in order to examine the effect of orientation and inclination on the rate of deposition. The model remained at the site for two consecutive annual runs. The main feature affecting the loss in glazing transmittance due to deposition was found to be extreme weather conditions, which in this context implies thunderstorms (heavy rains) and snow. Other meteorological factors, such as relative humidity and wind, also affected the deposition of airborne pollutants on the glazing, but to a lesser extent. The effect of seasonal changes was minimal. Glazing transmittance was seen to decrease (due to deposition of airborne pollutants) with the change in the angle of inclination of the glazing from the vertical to the horizontal.
